NASSM with immediate transverse rectus abdominis musculocutaneous reconstruction is a viable surgical treatment in breast cancer patients in any stage. Recurrence and complication rates for NASSM were similar to those for standard surgical breast cancer treatments.

The present study showed a continuous increase in the number of patients with breast cancer; the proportion of young patients, asymptomatic patients, early breast cancer, breast-conserving surgery, and immediate reconstruction after mastectomy; and the number of patients with risk factors. These results suggest that the clinical characteristics of Korean breast cancer patients reflect the patterns of Western countries.

BACKGROUND AND OBJECTIVES: Occult breast cancer (OBC) accounts for 0.3-1.0% of all breast cancers and is a rare presentation of the disease. The present retrospective study examined the overall survival and prognostic factors associated with OBC in Korea. METHOD: The study included 142 OBC patients identified from the Korean Breast Cancer Society cancer registry from January 1990 to December 2009. All patients had pathologically positive axillary lymph nodes (N1-N3) and pathologically and radiol

Prevalence and phenotype of BRCA mutation can vary by race. The purpose of this study is to evaluate the prevalence of BRCA1/2 mutations in non-familial breast cancer patients with high risks in Korea. A subset of 758 patients was selected for this study from the KOHBRA nationwide multicenter prospective cohort study. Mutations in BRCA1/2 genes were tested using fluorescent-conformation sensitive gel electrophoresis, denaturing high performance liquid chromatography or direct sequencing. Mutatio

The mismatch repair (MMR) gene plays a key role in the correction of DNA damage, and the loss of MMR has been implicated in resistance to a variety of chemotherapeutic drugs. The purpose of this study was to assess whether the reduced expression of hMLH1 and/or hMSH2 affects the chemotherapeutic responsiveness of sporadic invasive ductal carcinoma of the breast. Immunohistochemical studies were performed on 71 histologic specimens of breast cancer taken from the patients treated with surgery and

Hereditary breast carcinomas associated with BRCA1/2 mutations have unique clinicopathological and epidemiological characteristics. The objective of this study is to outline the prevalence, founder effect and clinicopathological characteristics of BRCA1/2 mutations for hereditary breast cancers from an analysis of reports recently published regarding Korean subjects. The prevalence of BRCA1 and/or BRCA2 mutations is 2.53.1% for sporadic breast cancers, 19.4-42.9% for familiar breast cancer patie

BACKGROUND: Malignant adenomyoepithelioma of the breast is a rare tumor and most of relevant literature consists of individual case reports. This study objective was designed to evaluate clinicopathological features and treatment outcomes of 15 cases of malignant adenomyoepithelioma at a single institute. METHODS: A retrospective medical record review was performed for 15 subjects confirmed with malignant adenomyoepithelioma upon postoperative pathological diagnosis at the Asan Medical Center fr

A standard procedure for single-port laparoscopic adrenal surgery has not been established. We retrospectively investigated intraoperative and postoperative outcomes after laparoscopic adrenalectomy through mono port (LAMP) and conventional laparoscopic adrenalectomy to assess the feasibility of LAMP. Between March 2008 and December 2009, 22 patients underwent adrenalectomy at the Department of Surgery, Kangbuk Samsung Hospital. Twelve patients underwent conventional laparoscopic adrenalectomy a

This study aimed to evaluate the prognosis of breast cancer patients who received neoadjuvant chemotherapy and underwent sentinel lymph node biopsy (SLNB) alone as axillary surgery regardless of their clinical and pathological lymph node status. We reviewed the records of 1,795 patients from Asan Medical Center who were diagnosed with stage I-III breast cancer and received neoadjuvant chemotherapy during 2003-2014. We selected 760 patients who underwent SLNB alone as axillary surgery and divided
